Abstract
A method and apparatus is provided for determining bandwidth allocation that includes initiating a transmission of a plurality of at least portions of content from a root node of a tree topology network along a path having a plurality of links connecting nodes to at least one destination node, allocating bandwidth for the plurality of at least portions of content carried on a respective link with an available bandwidth capacity such that a sum of the allocated bandwidths of all of the plurality of at least portions of content carried on the respective link does not exceed the available bandwidth capacity, and using a Lexicographic Minimax Algorithm for a Flexible or Constrained Bandwidth Allocation Model to provide bandwidth allocations to the plurality of at least portions of content and to determine an ordered list from the plurality of links from a most critical link to a least critical link.
